JOHN D. MADHIHA,`OF oHILLIoOrHH, OHIO. t

COAL- SPECIFICATION forming Be it known that I, JOHN D. MADEIRA, of Chillicothe, in the county of Ross and State of Ohio, have invented a new and useful Improvement in Coal-Cars, of which the following is a specification.

My invention relates to au improvement in that class of railway-vehicles (employed to transport coal, gravel, broken .rock, and other like materials) whose sides have one or more discharge-openings; and my invention relates to a provision, at each of such openings, of a pair of overlapping naps Orshutters, of which the inner shutter is hinged at the upper edge of the opening, and when closed becomes part of the car-side, and of which the outer and locking shutter' is hinged at the lower edge of the opening, and when closed secures and supports the inner shutter, and when open serves as the floor of an, extension -platform or disch argechute, as he reinafter fully explained.

In the accompanying drawings, Figure 1- represents, lby perspective view, a portion of a car-body embodying my invention, one opening being shown open. Figs. 2 and 3 are vertical sections through an opening in the closed and open conditions, respectively.

A A B are portions of the bottomframing of a car-body; P, a portion of the car-floor; C, out-sloped standards framed to the crosstimbers B and to the inner longitudinal timbers, A. D are oblique struts framed to said standards and to the outer longitudinal timbers, A. The body sides E rest against and are spiked or bolted to the sloping inner sides of the standards, so as to flare upward and outward in the manner shown. F are rectangular openings at equidistant intervals along the sides, said openings being preferably of width nearly equal to that between the consecutive standards, and extending from the hoor-level upward. Gr are wing-pieces spiked to the standards and struts, and having their opposing faces flush, or nearly so, withthe sides of the opening. vEach opening is provided wit-h a pair of overlapping shutters, as follows: H is an inner shutter, adapted to fit,

lSaid shutter is so hinged, as shown at I, by its upper edge tothe corresponding edge of the opening, as in the closed condition to side, (see Figs. l and 2,) but to be capable of l of my invention. f `1nentmay be applied'to a car with vertical CAR.

part of Letters Patent No.- 292,336, datedJanuary 22, 1884. Application {iled December 10, 1883. (No model.)

Y being held in the elevated position (shown in Figs. l and 3) by any suitable device, such as'a'staple and hook, J K.' yHinged, as shown at L, to the lower edge of theopening, and of equal width to and somewhat greater height than the opening, is an outer shutter, M, which,when closed, shuts tightly over and supports the closed inner shutter, being held to the said closed position by any suitable device, such as 'a gravitating catch, N. The said outside shutter, in its open condition, serves as the iioor of a discharge-chute, of which the wings G serve as the sides.

- rIhe described preferred construction may be modified in non-essential particulars without departing from the characteristic features For example, my improvesides and with an out-'sloped o'r any desired form of flor, and to openings placed at any height in the sides.

The inner shutter, instead of fitting the opening and closing iiush with the inner face of the body-side, may be larger than the opening, and may close on'the outer face of the body-side, the outer shutter in that case being hinged the thickness of the inner one farther out,

I claim as new and of my invention- 1. A car -body having one or more discharge-openings, each of which has hinged, respectively, to its upper and under edges,

two overlapping shutters, of which the inner shutter is held by the outer one when closed,

- and of which the outer shutter becomes, when open, the iioorof a discharge-chute, substantiallyas set forth.

2. In a railway-car for transporting coal and like materials, and having one or more discharge-openings, two overlapping shutters at each opening, of which the inner shutter` is hinged by its upper edge to the top of the opening, so' as to be capable of closing it, and of which the outer shutter is hinged to the bottom of the opening, and is combined with external side wings to form an extension-platform or discharge-chute, substantially as set forth.

In testimony of which invention I hereuntol IOO
